The shooting occurred at 9:41 p.m. in the 7100-block of South Artesian Avenue, police said. Two men, ages 18 and 59, were standing on the sidewalk when a man walked up to them an opened fire.

The 18-year-old man was shot in the back and chest and was transported to a hospital where he later died, police said. He has been identified to the Cook County Medical Examiner's Office as Tavion Roberson.

The 59-year-old man was wounded in the side and transported to Advocate Christ Hospital in serious condition.
